The branch stable/12 has been updated by mav: URL: https://cgit.FreeBSD.org/src/commit/?id=bc6d368bb8a359c557af200a93f2862f0571d6ea commit bc6d368bb8a359c557af200a93f2862f0571d6ea Author: Ryan Libby <rlibby@FreeBSD.org> AuthorDate: 2021-01-20 21:59:49 +0000 Commit: Alexander Motin <mav@FreeBSD.org> CommitDate: 2021-04-14 00:46:19 +0000 pms: handle maximum size IO with any alignment Define the maximum numbers of segments to allow for non-page alignment at the beginning and end of a maxphys size transfer. Also set ccb_pathinq.maxio consistent with maxphys.
